Abstract

We investigated differential gain, refractive index and (alpha) -parameter in strongly index and gain guided broad- area semiconductor optical amplifiers. The measured linewidth enhancement factor is larger than the values reported for narrow-stripe lasers and is consistent with theoretical predictions.
